Paint composition



Patented June 9, 1931 UNITED STATES JOHN R. DURBON, F JUNCTION CITY, KANSAS PAINT COMPOSITION No Drawing. Application filed June 14,

My invention relates to new and useful improvements in paint compositions and has for its primary object to provide such a paint composition particularly adapted for dressing automobile tops and the like.

Another object of my invention is to provide an improved paint composition of the above character which is absolutely waterproof and which may be used for a dressing 0 on either cloth, leather or any other material employed in the manufacture of automobile tops.

Another object of my invention is the provision of such an improved painting composition of the above character which produces a hard fast surface which is extremely elastic and which further will not scale or crack.

Another object of my invention is to provide such an improved automobile top dressing which consists of a minimum number of ingredients, all of which are readily obtainable and which may be easily and quickly compounded and applied to the automobile top with the expenditure of a minimum amount of time and labor.

My invention contemplates the production of a paint composition for dressing automobile tops preferably consisting of linseed oil, Japan drier and a conventional manufactured paint.

In preparaing the composition, I prefer to use the ingredients in about the following proportions: linseed oil, one-third; Japan drier, one-third; manufactured paint, onethird.

It will thus be seen that an equal amount of linseed oil, Japan drier and manufactured paint is used and the ingredients need simply be thoroughly mixed together to produce the improved composition.

The manufactured paint may be of any one of several different paints now on the market but I have found that in order to produce the very best results, the said paint should obtain approximately 12.5 percent pigment and 87.5 percent vehicle.

I have further found that the composition of the pigment and the composition of the vehicle in the paint should contain the fol- 1926. Serial N0. 115,962.

Also, I do not Wish to be limited to the particular manufactured paint set forth hereinabove as other pfitlints may be found which are just as desira e.

What is claimed is composition for dressing automobile tops and the like consisting of an equal amount of linseed oil,Japan drier and a paint, the paint consisting of 12 5/10 percent pigment and 87 5/10 percent vehicle, the pigment consisting of carbon 16 percent, calcium phosphate 77 percent, calcium carbonate 3 percent, silicate 2 percent, water 2 percent and the vehicle consisting of rosin 14 8/10 percent, fixed fatty oils 31 9/10 percent, ash 2 percent, and mineral spirits 51 3/10 per cent.

In testimony whereof I aflix my signature.
